Description
The cardiac muscle tissue, or myocardium, represents a unique form of striated muscle specialized for continuous and rhythmic contraction throughout life. It combines structural elements of both skeletal and smooth muscles while maintaining distinct features that enable high endurance, coordinated contraction, and self-regulation. The myocardium is composed of branched cardiomyocytes interconnected by intercalated discs that facilitate synchronized electrical and mechanical activity. Its ultrastructural organization supports aerobic metabolism and resistance to fatigue. This article describes the histological architecture of cardiac muscle tissue, its cellular and molecular components, and the functional adaptations that sustain cardiac performance and homeostasis.
